Out looking for some interesting flower pictures when I saw this little guy. He was all of 3 or 4mm in size. Tried using the Canon 100-400mm with extension tubes but the minimum focus distance was too far. I switched to the Canon 28-135mm with the extension tubes and got this. Canon 70D, Canon 28-135mm with 12, 20 and 36mm stacked extension tubes, 1/125sec, f/11 and ISO 1000.
